Time Period:  1950 | 1960 | 1970 | 1980 | 1990 | 2000

• October 4, 1957 - First Artificial Satellite

• October 1, 1958 - NASA is Born
  The National Aeronautics and Space Administration (NASA) is founded, taking over the responsibilities of the existing National Advisory Committee on Aeronautics.

• January 2, 1959 - First Spacecraft to Achieve Solar Orbit
